dont mean to be such a burden and asking you infinite questions, but i was reading up on the KCA-420i on alpines site and it made it sound that the adapter unit is optimized for 2004 or newer alpines. Mine is the CDA-7894 which i bought new probably back in 2000 or so. Although it Does have the ai-net adapter cord in back, im questioning whether it will be as easy to use, or show all the details that it claims to do.
If youre not sure i can ask my local audio shop so if its trouble dont worry about it. Thanks
